Abstract
Both ends of a valve stem in a valve body are respectively provided with a conventional spring and a shape memory alloy spring, wherein, the conventional spring is installed in the valve body, and the shape memory alloy spring is extended outside the valve body. The two springs are separated by a regulating nut, and are respectively supported. The setting of on-off temperatures of a valve is determined by phase transition temperatures of the shape memory alloy spring, and are regulated by the positions of the regulating nut in the valve body. The shape memory alloy self-controlling thermostatic switch valve has the advantages of simple structure, low cost, and reliable motion.
Description
The utility model is the heating power self-control thermostatic valve of liquid or gas constant temperature discharging in a kind of automatic control thermodynamic system.
The device that is generally used for controlling the discharging of liquid in the thermodynamic system or gas constant temperature has types such as electronic temp.-control valve, the gentle volumetric expansion valve of paraffin wax temperature-sensing valve.The electronic temp.-control valve adopts certain sensor to measure temperature signal, is converted into the open and close that electrical signal comes the control electromagnetic valve door through the complicated electronic circuit of a cover, reaches the constant temperature discharging.This electronic temp.-control valve is connected power supply and could be worked, not only circuit, complex structure, and consume energy.The gentle volumetric expansion valve of paraffin wax temperature-sensing valve is as sensing working medium with paraffin wax or certain gas, liquid or gas temperature raise in thermodynamic system, the paraffin wax fusing or the gas that are sealed in the container expand, promote the purpose that the interior transmission part of valve body reaches Open valve, these two kinds of temperature control valves are structure and processing technology complexity not only, and to the paraffin wax composition select for use or gaseous species select for use requirement very high.In addition, above-mentioned temperature control valve all has the more expensive shortcoming of price, is not suitable for being used for the family expenses thermodynamic system.
The utility model purpose is to adopt marmem as heat responsive element, and has the driving function simultaneously, thereby has solved the shortcoming of common used temperature control valve effectively.
Structure of the present utility model adopts two springs that are contained in respectively on the same valve rod, and one is conventional spring, and another is a shape memory alloy spring.Conventional spring is contained in valve inner, the one end press closer one with same valve rod all-in-one-piece slide block on, its the other end press closer one with adjusting nut one end of the inboard helical toothing of valve body, the other end supporting one shape memory alloy spring that is contained on the same valve rod the other end of adjusting nut, same valve rod passes in the middle of adjusting nut, memory alloy spring stretches out in the valve body outside, and is compressed by the nut that is spun on the valve rod by a pad that is contained on the valve rod.The valve body end that is positioned at shape memory alloy spring one side is connected with thermodynamic system, and the other end of valve body is connected with discharge pipe.It is I shape that slide block is processed into the longitudinal section, to reduce weight and to have made it better to neutrality.Pad sealing together is housed with throttle down reliably at the other end of slide block.Adjusting nut and slide block all have the axial hole of annular spread, in order to pass through liquid or gas.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a sectional drawing of the present utility model.
Among Fig. 1, memory alloy spring 9 is made by the copper-based shape memory alloy with suitable phase transition temperature, stretch out in the outside of valve body 5, and be contained in an end of valve rod 8, the one end is compressed by a nut 11 that is connected with valve rod 8 spirals by a pad 10 that is contained on the valve rod 8, the other end is bearing on the end groove of the adjusting nut 7 that is connected with valve body 5 inboard end spirals, the groove upper support one of the adjusting nut the other end is contained in the conventional biasing spring 6 on valve rod 8 the other ends that pass adjusting nut 7, conventional spring 6 stretches into the inside of valve body 5, its the other end is bearing in one, and to be processed into the longitudinal section be I shape, on the groove of slide block 4 one ends that fuse with the other end of valve rod 8, the other end of slide block 4 connects the floss hole that pad 3 sealing together is close to valve body 5, valve body 5 outsides are positioned at shape memory alloy spring 9 one ends and are connected with thermodynamic system, and the other end is connected with discharge pipe.The slide block 4 of adjusting nut 7 and I shape all is processed with the axial hole of annular spread, is convenient to liquid or gas flow.The turn of adjusting nut 7, both the pretension degree of can regulate biasing spring 6 was come the operating temperature that regulating valve opens and closes, and again as the sliding support of valve rod 8, it plays location and centering effect again with slide block simultaneously.When the liquid that enters valve body 5 from thermodynamic system or gas temperature are lower than setting value, shape memory alloy spring 9 is in martensitic state, elasticity is lower, in the bias voltage of conventional spring 6 and valve body 5, under the pressure acting in conjunction of liquid or gas and be in compressive state, act on the floss hole that slide block 4 makes it valve body 5 simultaneously.When the temperature of liquid in the valve body 5 or gas rises to setting value, shape memory alloy spring 9 is a parent phase by Martensitic transformation, recovery of shape becomes extended configuration, produce bigger power, surpass the bias voltage of biasing spring 6 and making a concerted effort of liquid in the valve body 5 or gas pressure, thereby make valve rod 8 open the floss hole of valve body 5 together with slide block 4 and sealing gasket 3 produces displacements, allow the liquid or the gas that are heated to setting temperature discharge, as soon as floss hole is opened, pressure in the valve body 5 rapidly disappears, the power that shape memory alloy spring produces substantially exceeds the bias voltage of biasing spring 6, thereby makes floss hole be opened to maximum rapidly.Because liquid or gas flow are continuous in the valve body, colder liquid or gas constantly replenish into from thermodynamic system, make valve body 5 interior liquid or gas temperature constantly descend, in case drop to when being lower than setting value, memory alloy spring 9 changes martensitic state again into, under the interior pressure effect of biasing spring 6 and liquid or gas, be compressed, and rapid throttle down.Like this close, open, close closed procedure, reached the purpose of constant temperature discharge liquid or gas.By round head bolt 1, packing ring 2 sealing gasket 3 is close on the slide block 4.
On-off valve of the present utility model, simple in structure, low price, easy to maintenance, be applicable to the occasion that needs thermostatically control discharge liquid or gas.Be specially adapted to solar water heater system, can improve the daily efficiency of solar water-heating system, and as required, can save or dwindle the solar water-heating system water tank capacity.
